The goal is to study the distribution of trace elements in environmental objects in conditionally clean territories and in territories under the influence of anthropogenic activities of the Ukrainian Polissya for ecological and geochemical assessment of territories. Research methods: general chemical analysis, granulometric, spectral, inductively coupled plasma mass spectrometry, statistical and cartographic data processing. It was found that the microelement composition of the studied soils of the Volynskiy, Kievskiy, Chernigovskiy and Novgorod-Severskiy Polissya generally corresponds to the natural regional background. Geochemical studies of a number of polygons in the background areas were performed for the first time. The low content of organic matter and the small amount of colloids in the composition of soils cause a relatively low sorption capacity. This leads to the danger of pollutants getting into natural underground and surface waters in the process of increasing technogenic load. It has been determined that the investigated small towns of Ukrainian Polissya are characterized, on average, by a moderately hazardous level of pollution. The content of heavy metals in soils increases with the presence of chemical industry enterprises in the city structure (Brovary, Shostka). Studies of the impact of man-made activities within urbanized areas on the natural waters of the Ukrainian Polissya are continued. The diversity of their macrocomponent composition, the presence of an increased amount of nitrates, chlorides, and iron are often associated with technogenic activity and require ecological and geochemical monitoring. For the vegetation of cities, a more intensive accumulation of microelements is observed in comparison with the vegetation of the background territories of the Ukrainian Polissya.
